The invention relates to crossing-bridge means, and more particularly to transportable ferries.Known transportable steam (application Germany N 1556954, CL 63 In 35/54, 1961), including the United butt nodes pontoon parts and tools automotive in the form of motor units.The disadvantage of this ferry is low performance on a wide water obstacle because of the limited speed.Also known transportable steam, comprising interconnected pontoon folding river and coastal links and means of motorisation in the form of motor units.Insufficient the Chennai speed.The purpose of the invention is to increase the speed of movement of the ferry, mainly on wide water obstacles.The objective is achieved by the fact that the boat is equipped with a turbojet engine, placed on self-propelled chassis, such as pontoon car, attached to the deck at the aft end of the ferry. Thus the longitudinal axis of the turbojet engine coincides with the longitudinal axis of the ferry.In Fig. 1 shows a transportable steam, side view; Fig.2 is a plan; Fig. 3 - river link, transom of Fig.4 - motor link, side view; Fig. 5 - node I in Fig.1; Fig.6 - node II in Fig.2; Fig.7 - cross section a-a in Fig.6.Transportable steam includes folding pontoon river units 1 installed between engine parts 2 and placed in the fore and aft extremities of the coastal ferry links 3 and 4. Every river and coastal link is made of two medium pontoons 5 and two outer pontoons 6. Coastal link differs from river wedge-shaped form. In the deck of the pontoons built roadway. Average and extreme pontoons are connected by hinges 7 and 8. In the open (operating) position the pontoons are closed deck locks 9 and bottom locks 10. On the transom medium pontoons ustanoveni with the possibility of longitudinal movement of the flat pins 13. Skew-symmetric location of the joining node and flat pins allows you to connect the links between themselves and with the engine links to any transom. Motor link consists of a housing 14 in which is placed the engine 15 and the propulsion and steering complex 16. In the deck of the hull is built roadway 17, and on the boards installed butt sites, butt identical nodes placed on the transom river links the Coastal units are equipped with lifts 18 for changing the angle of inclination of the links relative to the ferry. In the aft end of the ferry, established self-propelled chassis 19, for example, the pontoon vehicle on which the frame 20 is placed turbojet engine 21 to the fuel tank 22. The longitudinal axis of the turbojet engine coincides with the longitudinal axis of the ferry. Pontoon car secured to the deck of the ferry with the help of a chain or rope marks 23 to the eyebolts 24 embedded in the roadway medium pontoons designed for suspension parts for helicopters during their transportation by air. One end of the extension 23 is attached narashima to the frame 20 by means of brackets 25.The device operates as follows. After discharge of the water of river, coastal and motor parts on river and coastal links close tirem, the ear 12 and the flat pins 13. To the resulting tape is connected with both ends on coastal link 3. After lifting all coastal links with 18 lifts at some angle ferry served to the place of loading equipment. After loading the equipment on the ferry enters the pontoon car attached to the pontoon platform of the vehicle frame 20 is placed on it turbojet engine 21 and the fuel tank 22. Coastal link, located at the aft end of the ferry, raise and level it off the deck with the deck adjacent river level. At the aft end of the ferry pontoon set the car with a turbojet engine and fix it with the help of stretch marks 23 to the eye 24. The departure of the ferry from the shore performed by means of motor units. After installing the ferry boat on the set course include turbojet engine 21. During the movement of the ferry taxiing carried out using a jet propulsion engine parts. At some distance from the opposite shore turbojet engine off. The final approach to the banks carry out with the help of motor units. After unloading equipment steam with the help of motor units away from the opposite shore, razor and subsequent flights loading equipment and unloading are carried out by the coastal link, located in the bow of the ferry, and pushing off from shore, perform reverse. If necessary, refill the fuel tank turbojet engine produced during the loading equipment for the next flight. TRANSPORTABLE STEAM, comprising interconnected pontoon folding river and coastal links and means of motorisation in the form of motor units, characterized in that it is equipped with a turbojet engine, placed on self-propelled chassis mainly on pontoon car, attached to the deck at the aft end of the ferry, with the longitudinal axis of the turbojet engine coincides with the longitudinal axis of the ferry.
